PUMP.

Application filed July 21,

My present invention has reference to a centrifugal pump of a construction whereby liquid may be elevated. and distributed at a comparatively high rate of speed and in great volume so that the device is especially useful for irrigating purposes, but may also successfully be used in draining cotter-dams, handling muddy and gritty water, oils, tars and other heavy liquids as the improvement makes use of no plungers or other parts that will be injured by contact with such fluids.

An object is to provide a comparatively simple and thoroughly eliicient pump in which water or like fluid is elevated from a well or other source of supply, discharged into a suitable receiving tank without the employment of plunger-s, sucker rods and similar actuating devices.

A further object is the provision of a centrifugal pump in which a tubular member or casing is let in a fluid body and which has a normally closed inwardly open valve in the bottom thereof, there being supported on and in longitudinal alignment with said pipe a second pipe which is revoluble and which is supported in a novel manner to effect the least amount of friction between the said pipes and the supports therefor, the last mentioned pipe having its upper end received in a basin provided with a suitable outlet and its said end being formed with a nozzle whose passage is valve controlled, means being provided for priming the Well pipe, and means being also provided for revolving the fluid ejector pipe at desired speeds and in opposite directions, whereby the revolving of the said ejector pipe and the nozzle associated therewith will start the fluid from the well and thereafter the said fluid will be continuously elevated and ejected.

A further object is the provision of a centrifugal pump that shall comprise comparatively few simple parts, easily associated to produce an operative structure that may be cheaply set up or removed as occasion requires.

To the attainment of the foregoing and other objects which will present themselves as the nature of the invention is better understood, the improvement resides in certain novel features of construction, combination and operative association of parts, one of a number of satisfactory embod1 1926.

Figure 3 is a detail sectional view approX- imately on the line 3- 3 of Figure 2.

Figure lis a longitudinal sectional view through the nozzle.

By way of explanation I have illustrated my improvement in use with a dug well, it being, of course, understood that the same may be successfully employed'for elevating other fluid bodies.

The pipe through which the fluid is elevated or what I will term the well pipe, is indicated in the drawings by the numeral 1. The lower end of this pipe extends below the level of the fluid in the well 2 and this end of the pipe has screwed thereon a casing 3 whose bottom wall is open but provides a seat for the ball valve 4. The movement of the valve i when unseated, is limited by a laterally ext-ending element 5 in the casing 3. The pipe 1 extends above the well, the said well in the showing of the drawings being closed by a concrete top 6 and on this concrete body there is hired a metal plate 7 having a central boss 8 through which the well pipe 1 passes. A binding element?) passes through the boss and contacts with the-well pipe. Screwed on the well pipe and resting on the boss 8 there is a coupling 10 and screwed in the angle branch of this coupling there is a pipe 11 coupled to a vertical extension 152 provided, at its outer end, with a funnel member 13. The passage through the pipelQ is controlled bya hand operated valve let. Fluid is let in the funnel and directed through the pipe members 12 and 11 into the well pipe when the pump is to be primed.

On the disc or plate 7, and secured thereto by the means 16 that holds the said plate or disc on the body 6 there are the angle ends or foot portions of the upright members 17 of a metal frame. The uprights 1'7 are connected and held in spaced relation through the medium of brace plates 18'and 19. The members 18 and 19 have downwardly extending flanges which contact with the uprights and through these flanges and uplower end of this boss, the upper end of the well pipe 1 is received. Also received in this boss there is the lower end of a tubular shaft 22. Preferably there are anti frictlonal bearings between the eonfrontiln ends of the tubular shaft 22 and the well pipe 1 and the boss 21 provides a box having packing 23 that surrounds the confronting ends of the tubular members 22 and 1. The packing is held in the box by a cap member 24 which is adjustably. secured, by means 25, on the boss or packing box 21. The tubular shaft 22 has fixedly secured thereon a flange 26 that is received in, aflanged sleeve 27 which is screwed into a central opening in the brace plate 18. Between the flange 26 andthe sleeve 27 there are anti-frictional balls 28.

The brace plate 19 also has a central threaded opening therethrough in which is screwed a depending flange sleeve 29, that is also preferably fixed to the'said plate 19. Fixed on the tubular shaft 22, and received in the sleeve 29 there is a flange 30, and between this fiange and the sleeve there are anti-frictional balls 31.

Fixedly secured on the flanged top ofthe frame 17 there is the closedbottom of a basin 32. This basin has its bottom provided with k a central opening that is surrounded by an upwardly directed flange 33 through which ,the tubular shaft 22 passes. The basin 32 has oneof its sidesprovided with an outlet openin thatis surrounded by a fixed spout 34. The top of the tubular shaft 22 is flanged and bolted to this flange there is the flanged end of an anglecoupling 35 and secured to the outer fiange'of the coupling 35 there is the flan ed inner end of a nozzle 36.

The outer discharge end of the nozzle is reduced, and is indicated by the numeral 37. In and adjacent to the flanged end of the nozzle there is preferably integrally formed a spider 3S and slidable in the nozzle and normally contacting the. spider there is a tubular piston 39. The inner end of the piston is wholly open, but the outer end thereof is flanged, as at 40, to provldc a central opening. The wall provided by this opening 15 flared and provides a seat for a valve 41. A helical spring 42 is connected centrally between the valve 41 and the spider 38.

Fixed on the tubular shaft 22 there is a flywheel 43, and fixed above the fly wheel there is a pulley wheel 44. Trained around the pulley wheel there is a belt 45 that is operated by'any suitablesource of ower (not shown). In this connection it s ould be stated that other meansfor revolving the tubular shaft 22 may be employed, as for instance, there may be fixed on the said shaft a toothed wheel which is in mesh with a train of wheelswhose shafts are supported on suitable elements connected to the frame 17, and one of these gears may be provided with a handle whereby the tubular shaft 22 may be manually operated.

The pump is primed by pourin a fluid into the funnel but the valve controlled slidable piston in the nozzle renders the pump self-starting. This "is accomplished by revolving the pump so that the centrifugal force will cause the piston to move outwardly in the nozzle. The outward movement of the piston is limited by its contact with the shoulder 46 arranged in the barrel adacent to its reduced outlet end. In such outward movement the valve =l-1 holds the piston closed so that a vacuum or suction is thus created. The pump is then slowed down which permits the spring 42 to in fluence the piston and its valve in an opposite direction and to initial position. Thus by speeding and slowing down the pump the piston will be caused to move in opposite directions in the nozzle and thereby create suliicient suction or a sufiicient vacuum to the nozzle. \Vhen the water is flowing and the pump is revolved at a definite speed the force of "water against the piston will have moved the said piston against the stop shoulder 46 and such force of water will hold the valve 41 opened. When the pump is not in operation the piston will, tirough the medium of the spring 42, return to initial position My improvement is of a comparatively simple nature and, as previously stated, may be easily erected or dismounted when not desired as a permanent fixture. "With the improvement a large volume offiuid can be elevated and delivered through the outlet 34 in an easy and expeditious manner, and the flow of the fluid through the pipe can be regulated by the velocity in which the tubular shaft 22 is operated. The improvement, is, of course, susceptible to changes and modifications and therefore, I do not wish to be restricted to the precise structural details herein set forth as I hold myself entitled to make such changes therefrom as fairly fall within the scope of what I claim without departing from the spirit of or sacrificing any of the advantages of the invention.

Havingdescribed the invention, I claim 1. A centrifugal pump including a well pipe having its lower portion arranged in a body of fluid and an inwardly opening valve at the bottom of said pipe, a tubular shaft arranged above and in a line with the well pipe, packing between "the shaft and pipe, anti-frictional bearings supporting the tubular shaft and holding the same from longitudinal movement, a nozzle arranged at an angle on the outer end of the tubular shaft, means for revolving the shaft, a tubular piston in the nozzle, an outwardly movable valve for the piston, a spring fixed at one end of the nozzle connected with the valve and urging the valve in a direction to close the tubular piston and to urge the piston toward the axes of the shaft, and means limiting the sliding movement of the piston in the nozzle 2.
